To all whom it may concern:

Be i known that I, HARVEY L. FisHER, a citizen` of the United States,residing at Woodstock, inthe county of McHenry land State of Illinois,have invented certain new l and useful Im rovements in T pe-Writers,

of which the. fo lowing is aspeci cation.

This invention relates to improvements in typewriting`machiiies, and'while it compre.

hends features which are applicable to typewriters of any construction,all the features of the invention are particularly applicablel to atypewriter designed for` producing exposed writing, that is, writingthat is visible, letten-by letter, as it proceeds; and it is inconnection with such a machine that I have.

herein` illustrated myinvention.

' The principal objects of my invention are the following: First. Therovision ofaplaten feed and escapement mec anism, comprising a rack andpinion, of such character thatthe carriage may; be moved freely back andforth without disconnection or separation of therack andpinion. Second.The provision of` a detent mechanism for the escapement controlling thepinion of the carriage feed mechanism, which maybe disconnected from, or

thrown out of'engagement with, the escapement so as to permlt the freeaction thereof and consequently of the pinion without disengagement fromthe, rack. Third. To insure the proper lineY spacing of the'paper feedmechanism, notwithstanding the shifting of the carriage for upper andlower case type, andthis without shifting the position of the i feedmechanism which shall b'e stationary relative to theplaten.` Fourth. Theutilization of thepape'r feed roll. to line upv the sheet orA sheets,when inserted in the machine, and to insure the maintenance of suchalinement, and at the same ltime prevent the shiftingoof the sheets ofpaper upon one. .another while being fed into the machine.l Fifth. Thepro'- visi'on of double universal spacing mechanism whereby lthecarriage feed mechanism alone will be operated ,byf-the spacingv bar,while both the carriage feed and printing mechanism will be operatedbythe key bars, and

vthis regardless of whether the platen is shifted forl either the upperor lower case. Sixth. The provision of means for locking and releasingthe shifting'mechanism for theY platen, whereby the machine is adaptedfor the continuous writing of either upper or lower case type, orfor theconsecutivewriting of as many letters of either case as the. operatormay desire. Seventh. The provision -of a novel ribbon throw mechanism,whereby the ribbon is promptly thrown under the type and removed fromover the writing at each Operation of a key lever, so as to avoidobscuring the writing'except at the instant-a letter is made, and thisnotwithstanding the shifting of the. platen/for the writing of eitherupper or lower ca'se letters. These and such other objects as mahereinafter appear are attained by the devices illustrated in theaccompanying drawings, in which- Figure 1 represents a plan viewI of amachine embodying my invention, the type ribbon beingillustratedby'dotted lines and the type being removed' from the type bars vforclearness of illustration.' Fig. 2 repre* sents a middle verticalsection of the machine. Fig. 3 represents a plan yiew of the frame ofthe machine .with the carriage, ty e detent, rack and pinion of thecarriage feed mechanism, showing the same in different positions. Fig. 7is a detail rear elevation of the escapeinent devices. Figs. 8 and 9 arc.detailed elevations of the paper vfeed mechanism showing 'the' same indifferent positions. Fig. l() is a detail view of the adjustable stopfor thel spacing lever and platen-actuating pawl. Fig. 11 is a detailedsepltion more Aclearly showing the paper feed ro s. z

Similar lettersofreference indicate the same parts in the severalfigures of the draw- Referring now by letter to theaccompanydrawings,.Ajindicates the main frame of my machine, which is generallyrectangular in plan View and provided with an extension B at the frontto receive the key-board, this frame being preferably formed of' castmetal and so shaped as to best adapt it'for supupwardly and rearwardlyinclined extension,

Fi". 2, arc four bearing plates E, Fig. `1, iny

which are journaled the axles or pivots of the type-bars F. Thisparticular method of arranging and supporting'the type-bars consitesides of the machine.

stitutes the subject-matter of a separate application, Serial No.706,481, filed February 23, 1899, and it will suffice' here to say thatthe bearing plates E lare so arranged, and the axles of the type-barssojournaled in them, that the types upon the extremities of the type-barswill all strike at the same point when the bars are operated. Thetype-blocks are securedto the respective bars F at such varying angles.to the. bodies of the bars as to cause all of the type-blocks to strikethe platen at right-angles to its axis, as usual in machines in whicheach typeebar carries both an upper and lower case letter or character.i Y

Each type-bar is provided near its lower end, Fig. 2, with a rearwardlyprojecting ear J to which is pivotallyconnected the upper end of a rod4whose lower end is connected with the kefjflleverv L, so that when thefront end ofthe lever is depressed vthe upper end of-the type-bar willbe swung rearward and downward into contact with the platen, to effectthe printing.

When in normal position the upper ends of the typesb'ars F rest againsttype-rests M carried by brackets N supported' upon the plate D, Figs. 1and 2.

The transversely movable paperlcarriage in which the platen C is'mountedcomprises a rectangular frame Q, whose forward side, near its middle,Fig. 2, is mounted a roller Rwhich travels upon a lfixed rod or rail Sof the lframework and-su ports the forward side of the carriage. T erear ends of the two opposite side arms of the frame Q are secured to atransverse rod T, Fig. 1, which is adapted to slide longitudinally inguides T5 upon the main frame A of the machine. The platen C issupported at its opposite ends upon arms U, Figs. 1, 2, 8, and 11,secured to and projecting upwardly and forwardly from a rock-shaft Vwhich is journaled' at its opposite ends in the side arms of the papercarriage frame Q.

Secured to and projecting forwardly from the rock-shaft V is a 'shortarm WV, Fig. 2, which has secured to it the upper ends of twospring-arms a a which have mounted upon brackets b b secured to theirlower ends two anti-friction rollers c c embracing and adapted Figs. land 2, upon' to travel longitudinally upon a rod X carried by a pair ofbell-crank levers Y which are se-V cured, at the opposite sides of themachine, upon -a rock-shaft Z. Each of` the bell cranks Y is providedupon the front end of its lower horizontal arrnv with an inwardlyvprojecting lug or foot 7L, Figs. 2 and 3, which ugs underlie theshift-keys g upon the oppo- When either one of said keys g is depressedthe shaft Zlwillbe rocked and the rod X thrown forward,

wardly from the supporting 'threaded through i projection 7i', Fig.

Athereby rocking the shaft V and swinging the platen C upward andrearward, into position for the printing of upper-case characters.

The Ipressure of the anti-friction rollers cc upon t e of the armsa a,is regulated by means of a shift rod X, under the spring actionset-screw d passing through one of the y brackets b and engagingtheinner face of the opposite arm or bracket b.

The upward and rearward movement of the platen C, under the action ofthe'shiftkeys g, is limited by stops f, Fig. 2,-with which contact shortarms e projecting rear-- arms U ofthe platen, the stopsf in the presentinstance beingadjustable and l projecting lugs provided for the 'purposeupon the paper carriage frame Q, Figs. 8 and 11. y j

For the purpose of locking 4the platen C in shifted position when 'theyshift-key g at the right side of the machine is depressed, and forreleasing it when the shift-key at the left side of 'the machine isdepressed, the following devicesare provided, reference being had toFigs. 2 and 3: Hung upon a stud h pro j ecting inward from the leftAhand side frame of the machine is a latch i in the form of a bell-crankhaving its upper and forwardly extending horizontal arm y' weighted soas to swing the lower end of its depending arm rearward when permittedto do so. The depending arm of this bell crank latch nor-- mally restsagainst the forward end of the bell-crank Y at the left side of themachine, so that if'the front end of said bell-crank be depressed thelower end of the latch I will swing rearward overv the front end of thebell-crank Y and hold the latter depressed, thereby locking the platenin shiftedv posi tion, This occurs whenever the shift-key at the rightside of the machine is operated, since the effect of depressing such keyis to rock the shaft Z an bell-cranks Y, as heretofore explained; Theshift-key Gjat the left sideof the machine, however, is provided with alateral 3, adapted when the key is depressed to engage the dependingarr'n of the latch i and sw ing it forward,` thereby preventing itsengaging the front end of the bell crank Y and locking the latter indepressed position. ll'lien, therefore, the shift-key g at the left sideof the machine is depressed the platen C returns to its normal positionas soon as the key is released. So, also, if the shift-key at the rightside of the machine has been operated, and the platen thereby locked inshifted position, the depression of the shift-ke y at the left side ofthe machine Awill release the platen, since the projection 7c upon suchkey will Contact with the rear side of the latch i and swing the latterforward, thereby disengaging it from the frontend of d depress Ythefront ends of bothI consisting of screws Y' the bell-crank Y with whichit had been engaged at the operation ot the shift-key at the right sideof the machine.

The means for advancing the paper carriage to the lett step by step, atthe operations of the type-keys and space-bar, is as follows,- it beingundertsood that the paper carriage is normally pulled toward the left bya suitable spring inclosed within a drum or casing X', Fig. 2: The papercarriage trame Q has secured to its rear side a horizontal rack-bar m,Figs. 1 and 2, which constant-ly meshes with a pinion njsecnred npon ashort vertical shaft o suitably journaled in the frameA. Secured to thelower end of the shaft o is an escape-4 inent wheel p having itsdepending flange or rim cut to form alternating teeth and notches, asshov. n in Figs. 2 and 7.. The action of the paper carriage springtendsto turn this esrapeinent wheel 71 in the direction of the are vousupon it in Figs. 4, 5 and 6, these latter viens being bottom plan viewsof the parts shown in them and the direction ot movenient of the pari sindicated by the arrows being consequently the reverse of that in thetop plan view in Fig. 1. The devices cop-` era-ting with the escapementwheel p, to permit the intermittent advance of the 'paper ,cnrriage, areshow n most clearly in these latter vien s, where g is a lever pivotedat g to a depending stud p upon the under side of the top plate A of"the main frame of "the machine, Fig. 7. Also pivoted at g is one end ofan arm r which has pivoted to its o po site end a short lever s havingon one sidb of its tulcrum or pivot athin horizontal end against whichbears one end of a spring u secured. at its opposite end to the lever q,and having upon the opposite side of its fulcrum or pivot a thinvertical end ortooth t adapted to pass through the notches in theescapement wheel p. The end. ot the lever q is provided with a notch orrecess to receive the tooth t n hen the latter is in the position shownin Fig. 4, and it is also provided upon its upper side ith a lug rwhich, when the parts are in the position shown in Fig. 4, is in line nith the tooth t of the escav ement lever s. The spring u bears against te end of' the lever `s one side ot its middle line and tends to rocksaid lever upon its fulcrum and throw it to the position shown in Fig.5, but when the parts are in the position shown in Fig. 4v the lever isheld in the position there shown, against the stress otthe spring u, bythe stress of the paper carriage spring tending to turn the escapement nheel p in the direction of the arrow. When, however, the lever y is snung to the position shown in Fig. 5 the tooth t of the esca-pement lever.s ill be withdrann inward' frontengagemeiit with the not eh of theesrapement n heel p in n hich l it had been resting and` the tooth rrupon the lever g will enter such notch and hold the wheel pin timedposition and prevent its be- 1 ing turned forward in the direction otthe arrow notwithstanding the disengagement of the lever s from it. Assoon as the tooth t of the escapement lever, at the inward movement ofthe parts from the position of Fig. 4 to that of Figy 5, becomesdisengaged from the esca ement wheetp the spring u will throw the everto the position shown in Fig. 5, in which position its tooth-t willstand o posite the next succeeding notch in the w'eel prV It, now, thelever g be moved to the position shown in Fig. 4 the tooth t of theescapement lever will pass outward through such succeeding notch in thewheel p, and as soon' as the parts have moved outward tar enough todisengage the lug r Jfrom the wheel p the paper carriage spring will befree to advance the paper carriage and rack m and turn the escapementwheel in the direction of the' arrow until the tooth t of the leverscontacts with and is arrested by the end of the lever q in the positionshown in Fig. 4. In this manner and bythes'e means the movement ofthelever fromthe position shown in Fig. 4 to that shown in Fig. 5 and thenback to that shown in Fig. 4 will permit the scapement wheel p to turnthe space of one notch or tooth, and thereby permit the paper carriageto advance one step. The-movement of the lever gin one direction, forthis purpose, is

effected by a coiled springe connected at one y end to the lever and atits opposite endto the frame A, and its movement in the oppositedirection is eti1 ected by means of a universal bar w, Figs. 2 and 3,underlying all of the type-levers L and the two side levers of thespaceebar l, said bar w being carried by the Jfront ends of armslsecured at their rear ends to a rock-shaft y, which rock-.shaft hassecured to and. projecting upwardly from it,

near its middle, Aan larm z whoseupper end` bears against or is adaptedtoengage a lug s upon the under side of the lever q, Figs. 2, 4, and 5.When, therefore, the s ace-bar Z or any one of the type-levers is t'epressed the end ot the lever q adjacent'the escapement wheel )l w illbe thrown forward from the p0# sition shown in Fig. 4 to that show-n `inFig. 5, and when the space-bar or operated typelever is released thespring o will return4 the parts to the position shown in Fig. 4, withthe result that vthe paper carriage will bey advanced one step asdescribed.

K guard against the contingency of the tooth t ot' the esrapeln-rlitlever .Q by any possibility engaging and becoming bound` against theinner surface of the cscapement wheel p when moving outward from th(`position ol' separate members yieldingly connected together andoperating as described.

The paper carlriage is at all times free to be returned to or towardright hand position by simply pressing it in .that direction, suchmovement of the paper carriage simply turning the escapementwheel 4pbackward or in a .direction opposite to that indicated by the arrow inFig. 4, with the result that the escape'ment lever s will be swung uponits pivot bythe turning of the wheel'until its tooth t slips out of thenotch in the wheel with which it has .been engaged, after which, duringthe further backward movement of the wheel,

the'end of the tooth will ride idly over the inner surface of thedepending flange of the v Wheel; but for., the purpose of enabling theaperparriage to be freely moved toward the upon spools mounted 1n thecaslngs 38, each eft without manipulating any of the key levers or thespacing bar, as well as forthe purpose of permitting it to be movedtoward'.

the right without any engagement whatever of the lever tooth ,t with thewheel, I provide means for moving the lever g to the extreme forwardposition shown in Fig. 6, thereby entirely disengaging both its lug 71and the tooth t of the escapement lever s from the wheel p. and leavingthe latter free to turn in either direction, andthereby leaving thepaper carriage to be'freely shifted back and forth. Such means consistsof a thin bar or plate 13 mounted'upon the paper carriage frame Qandextending longitudinally of the rack bar m immediately beneath thelatter, Figs. 1, -2and 8. As shownin Figfl the plate 13 is. providedwith two parallel oblique slots 14A-*14 through which pass pins orscrews 15 projecting from the paper carriage frame and cinistituting theconnection of the plate 13 with said frame. A rod 17 is connected at itsright hand end to a forwardly' projecting ear upon. the' plate 13, andat its eft hand end projects beyond the side frame of thev machine andis provided with a pushbutton 1R. A spring 16 connected at its `righthand end to the plate 13, near the right hand end vof thel latter, andat its left hand end to the frame Q, pulls the plate 13 toward vthe leftand yieldingly holds it in the normal position shown in .F 1. t W'hcn,however, the plate is slid toward the right by pressing upon the button18 of the rod 17 the plate will also, owing to its connection with theIframe by the oblique slots 14. and p/ins 15, be moved rearwardly fromthe position shown in Figs. 1 and 4, to the position shown in Fig. 6.

anti-friction relier 12 mounted upon thc upturned forward end of an armg projecting i At such rearward 'movemeiit the rear edge ol` the plaie13 will contact with an i Fig. 5 to that of Fig. 4, I provide the twowith the roller 12 rocks'said bell crankl from the position shown inFig. 4 to that shownin Fig. 6, and thereby disengages both the lug 1 ofthe lever g and the escapemerit lever. tooth tfrom the-escapementwheelp. v The paper carriage will then be free to be moved in eitherdirection, the pinion n and escapement wheel p' being idly turned by therack m during such` movement 'and the roller 12 upon the bell-cranklever traveling along the rear edge ofthe plate 13. the push-button 1,8is released thespring 1.6 will restore the parts to normal "positionshown in Figs. 1 and 4 and rengage the es- Acapement devices'whichcontrol tie move-y ments of the paper carriage under the opera-- tionsof the keys and spacing bar.

The inking ribbon 52, shown in dotted lines in Fig. 1, is wound at itsopposite ends Vhen pressure on spool being provided upon its rear side,outside the casing, with 'a ratchet 4l which is engaged by' the u perend of a pawl 42, Fig. 2, which is pivote at its lower end to an arm,'43 on the rock-shaft 9, it .being understood y that there are twopawls 42 connected toA two separate arms 43 at the opposite ends of therock-shaft 9 and coperating with the ratchets41 of the respective ribbonspools. A' universal bar 11, underlying all of the` type-levers but notthe space-bar levers,

Fig. 3, is supported by arms 10 secured to and projecting rearwardlyfrom the rockshaft 9, so that whenever any type-lever is depressed theshaft 9 will be rocked and the pawls 42 thrown upwards. Suitable means,not shown, is provided for holding one of the pawls 42 out ofcooperation with its ratchet 41 while the opposite pawl is incooperation with its ratchet, so that the ribbon will be shifted in onedirection or the other according to the adjustment ofthe pawls.

In its passage from `one ribbon spool to the other the 'ribbon 52 is ledthrough guideways 2 upon the upper rear end of a reciproeatingribbon-throw 3 consisting, in the particular form shown, of a forked `oryokeshaped plate suitably guided to reciprocate Abackwardly andforwardly upon the forwardly and vrearwardly inclined portion of thcbracket plate D which supports the bearing plates E for the type-bars,Figs. 1 and 2. The upper rear ends of theA two arms of this ribbon-throwplate are reversely bent and provided with upwardly projecting lugs, toform guide-ways for the retention and passage of the ribbon. To theunder side of the plate 3 near its lower forward end is'pivoted theupper end of the vertical arm 4 of a bent lever, whose other arm extendsrearwardlyY and is pivotally conneetechto the upper end of an arm 6 fastat its lower end upon the rock-shaft Z, Fig. 2. Pivotally connected torear end of an arm or link 7 whoselowei forhaving q as its pivot or thebent lever 4--5, at its angle, is the upper ward end isv pivoted to theupper end of an arm 8 fastened at its lower end to the rockshaft 9,which rock-shaft, as ,beforel exbut when any type-leveris depressed andtype-bar.

' is necessary to -bring the shaft 9 'thereby rocked the connection ofsaid shaft with the ribbon-throw plate, through vthe medium ofthe arm 8,link 7, and lever-arm 4, will slide the ribbon-throw plate- 3 upward andrearwardl and carry the ribbon into the path of the typ This is theoperation for the printing of lower-case letters and characters, but.when the platen C is swung rearward b y the operation of one of theshift-keys in the manner heretofore explained, for the printing ofupper-case letters and characters, it that the ribbon shall be carriedfurther rearward by the ribbon-throw, so as it over the line of Iprintupon the platen in the shifted positionof the latter. rl`his is effectedby means ofthe connection of the rock-shaft Z with the bent/lever 4-5through the medium of the arm 6. Whenever either one of the shift-keysis depressed, to shift the laten C to upper-case position, the shaft Z1s,rocl ed in the manner heretofore explained, thereby throwing forwardthe upper end of the arm 6 and consequently moving forward the point ofpivotal connection between the link 7 and bent lever 4--5 andstraightening out the toggle formed by said link and the arm 4 of thebent lever, also`slightly rocking the latter on the pivot of its angle,with the result that the ribbonthrowfplate 3 will be slid upward andrearward a proportionate distance, and. when the type-lever is thendepressed and the shaft 9 rocked its arm "5i, operatingupon theribbon-throw plate through the link 7 and arm 4 of the bent lever, willmove the ribbon throw plate rearward to the necessary position for theprinting of the upper-case characters. l For the purpose ol rotating theplaten (l, for line spacing, the platen has secured upon the right handend of its projecting s indle a ratchet 19, Figs. l, 8, and 9, with W'lich cooperates the upper end of a hook pawl 22 which in the presentinstance is in the form of a bell-crank lever pivoted at its angle uponthe depending rear end of the spacing lever 2l. A spring 2lu coiledaround the pivot of the lever 2l andfsecured at one end to saidv leverand at its opposite end to the paper carriage frame Q yleldingly holdsthe lever 1n the position-shown with the depending arm of the pawl lever22 `bearing against the lower forward edge of a pivoted stop 24 platelholds theribbon 52 t'o the front.

'22 and causes the dev ending arm'oe'upon the 1 u on theframe'Q, thisstop serving to limit t e movement of the lever 2l under the stress ofits spring 21,

Coiled around the pivot. of 22--23 vis as ring 22a connected at one endto the depen ing arm of the spacing `lever V21 and at its opposlte endto the depending arm 23 of the pawl lever and exerting itsfforc'e .in

the pawl lever a direction which tends to spread the two arms of thelevers a art as shown in Fig. 9. In normal position, d the spring 21akovercomesthatof the -ring n i the spacing lever topress t e dependingarm of t e pawl-lever a alnst the stop 24 and maintain the ends o 'thetwo levers in contact with each other, asin Fig. 8. Whenever the frontend of the s acing lever 21 is lifted by hand, however, t e spring221'will be permitted tol actr1 and will at once'rock the pawll owever,the tension of` lever upon pivot and throw its upper rear`v r end intoengagement with the ratchet 19, after which any further movement of thespacing-lever 21 will cause the pawl to turn t e ratchet and platen.

As shown in Fig'lO the stop 24 consists of a pivoted plate or lever ofsuch shape that when in one position it will present a contact. surfacec to the depending arm 23 of the pawl lever which will arrest therearward movement of the depending arm of the spacing-lever 2-1, (underthe action ofitsspring 21a) at agiven point, and whenin anotherpositiomwill present a Contact surface af"A which will arrest 1t at aomt forward of the one just mentioned. hen in the position shown inthedrawings the stop permits a maximum rearward movement of the parts, andconsequently a maximum length of forward movement when the front end ofthe spacing lever is lifted byhand from the position shown in Fig. 8 tothat shown in Fig. 9; and inasmuch as' thep'awl 22 -is thrown intoengagement with the ratchet 19 by the spring 22" soon as the front endof the spacing lever 2] is lifted, it follows that with the stop 24 inthe position shown in the drawings movement of the spacing lever 2l to te position. shown in Fig. S) will impart a maximum movement to theratchet lf.) and platen l, andv advance the platen a .-"full space.When, however, the stop late/24 is swung to position to present itsother contactsurface m to the depending arm 23 ofthe pawl lever theparts will be arrested and maintained in a norm al ositiou forwardof/that shown in Fig. S, wit i the result that a movement ofthe spacinglever from .that position to the position shown in Fig; 9 will advancethe ratchet 1Q and platen C but one-half the distance which they areadvanced under the other adjustment of the stop, or, in other Words, ahalf space. i

The adjustment and proportion of the parts are such that,notwithstanding the fact sitions or the other, the only dinerence beingsist of two rollers 26 26, (Figs. 2 and 11),

that the spacing lever and actuating pawl for the platen ratchet aremounted upon the paper carriage frame Q, instead of being mounted uponthe swinging `platen frame Ll, thev pawl willv coperatc with the ratchetin the manner and with the result above described whether the platen bein one or its shifted pothat when the platen is swung rearward toupper-case position .the pawlz2 will, when the spacing lever isoperated, engage the ratchet 19 one notch or tooth in advance or thepoint at which it 4would engage it if 'the platen were in its normalforward position. After its engagement with the ratchet the furthermovement of the spacing lever will cause the pawl to turn the ratchetplaten one` space or two spaces, according to the'adj ustment of thestop 24, whether the platen bein one of its shifted positions or theother.

A. roller 26 carried by a spring arm 20al secured at its lower end toone or the supporting arms U of the yplaten bears againstJ the ratchet19 and serves as a brake and arresting pawl for the ratchet and platen.

The spindle of the platen has secured to its extreme ends thehand-wheels35 by which the platen may be turned back and forth at any timeindependently of the spacing mechanism above described.

The feed-rollers which coperate with the platen to advance or retractthe paper as the platen is turned forward or backward conjournaled attheir opposite ends in the upper and lower ends of the two opposite sidearms 25 of a pivoted frame composed of said side arms and a curvedcross-plate 25a connecting them and. curved to conform to the forwardface of the platen. The side arms 25 of this frame are pivoted at 27 tothe upper forward ends of a pair of arms 28 secured at their lower rearends to the opposite ends of a rocleshaft 30, which rock-shaft isjournaled at its opposite ends in two short arms 3l .projectingforwardly from the lower ends of the platen-supporting arms U, orotherwise 'made fast upon the rock-shaft V. The rockshaft 3() has fastupon it near its middle a rearwardly projecting arm 32 provided with alaterally projecting stud to which is connected one end of a spring 33whose opposite end is connected to the rock-shaft V. The tension of thisspring tends to force the rear endvof the arm 32 downward and rock theshaft 3() in a direction to force the feed-rollers 26 against the platenC, as shown in Fig. 2. The shaft 30 has secured upon its right hand,end, Figs. l andv 8,l a handle; 34 by the feed rollers 26 are mountedalsoghave journaled in them athird roller 29 which is' normally out ofcontact with the platen C, asl in Fig. A2, but adapted to be thrown intocontact therewith 4whenever the shaft' 30 is rocked by means of thehandle 34 to throw the feed rollers 26 forward' to the position shown inFig-1l. l i,

The above described construction and arrangement of parts isparticularly advantageous where the' machine is being used formanifolding work, and a considerable number of sheets of'paper, withinterposedcarbon sheets, have to be inserted between the platen and feedrollers. The front ends of such sheets are inserted from the rear be-`tween the platen C and 'roller 29 when the parts are in normal positionas in Fig. 2, and are pressed forward until they abut against the lowerfeed roller 26, the roller 29 serving as a guide for the insertion ofthe front ends of the sheets andthe roller 26 serving as a longitudinalstop against which theymay be straightened ,and lined up. Upon thenlift.- ing the rear end yof the handle 34 (Fig. 8) with the rightl handthe roller 29 will be 11 and caused to firmly grip the front ends of theinserted sheets betweenitself and the platen C, 'the feed rollers 2 6being at the same time thrown forward to permit the freel passage of theends of the inserted sheets be' tween them; YVith the parts held in thisposition with his right hand theoperator can turn the platen C forwardwith his left hand until the sheets .have been advanced far enoughfortheir upper front ends to have then releasing the handle 34 thespring 33 will instantlyretn'rn thev parts to the position shown in Fig.2 and cause the rollers 26 to grip the paper between themselves and theplaten, after which the paper will be further advanced by the turning ofthe platen, I either by handv or by means of the spacing mechanism.

The arrangement of the rollers coperating with the platen in the mannerabove de-5 scribed `is not only advantageous in connec tion the initialintroduction of the pa! per into the machine, particularlyin manifoldingwork, but it has an advantage in connection with the adjustment of thepaper from time to. time while it is being written upon, since by moving.the handle 34 to middle position the three rollers 26, 26, and 29 mayall be held out of engagement with the' platen, thus entirely releasingthe paper and permitting it to be freely adjusted up and means of whichthe shaft may be rocked in the opposite direction and the feed rollers26 thrown forward away from the platen C, as j shown in Fig. 11, j Thoside arms 28 which are fast vupon the rock-shaft 3() and carry the framein which down or sidewise, as occasion may require or may be desirable,after' which by simply releasing the handle 34 the paper will be firmlygripped between the rollers 26 and platen acam. .l
